To allem am mem.- Be it known t at I, JOHN J. KELLY, a

citzenkof the United States, and a resident- ,O'fWhiting, in the county 'of Lake and State Hof 'Indiana, have invented a new and lmroved-HobWater Tank, of which the fol-- ".lbwing is a full, clear, and exact description.

i llfllhisfinvention is an Airriprovenfient in hot I v"Water jtanks such as are ordinarily used in connection With'cooking ranges for heating Water 'for domestic purposes, and has 1n viewl the provision of a Vgas heater 'in connection ivithithe tank, to heat the .Water when therevz-in therange is out, orto be .15

used as ani-'auxiliary heater or' as the sole "1 heater of tblre'f'water, as desired. n, The invention consists of an upright hot' water storage'tank, a feed pipe and a hot Water returmpi e respectively leading from and leading to't e tank, a vertical flue passing through' the tank, .and a chain heat collector suspended in the iue, with the links thereof, hanging vertically, of less transverse diameter than the internal diameter of the liuc', and fsp'aced from the Walls of the flue,

and thel successive links having approximately equalcross-sectional areas.

Reference iis-:to be had to the accompany- .ing .drawings forming a part of this speciiication, in which' similar characters 'of reifere'nce' indicate corresponding parts in all the f views.

Figure l is a central vertical section of a hotwater tank embodying my invention;

Fig. 2 is a plan of the saine; and Fig. 3 is I a cross-section substantially on the line 3-3 of ligv` l.

The tank proper, as shown, is of the con y ventional form, and is in the nature of a long cylindrical. body esupported in an upright position on a suitable base 6 but mayv be of any desired construction, and to which my im )rovements are applicable. At

f the "sident t e tank l have shown pipes 7 and 253,'l respectively leading .to and from the heating coil of the range, a' drain pipe 9 i leading from therbottom. of the tank, a sup- `ply pipe 10 and a discharge pipe 11, leading ,resoectively to the lower portion of the tank an fronithe upper Yportion of the tank, all of whiclr'pipes are common lto hot Water tanks of this character, for which reason further reference to them 1s deemed unnecessary.

In ap lying 1n improvements to the tank, .5, I ma ce use o a vertical iiue l2, vand expand its ends in theV opposite heads of the tank, the flue being preferablyy centrally arranged. 'In the fork of the stand 6 is seated a burner 13, which for convenience of illustration I have shown as an ordinary Bunsen burner, which is suitably connected with the gas supply. At the top of the tank is secured a spider or similar device lll, bridging over the upper end of the flue, for receiving and Supporting the threaded shank of a hook 15, `from which is suspended inthe flue a chain heat collector 16, the links of Which hang vertically, are of .less diameter than the internal diameter of the flue, and With the successive links of approximately the v same cross-sectional area; the heat collector extends to or closely adjacentto the llame These disks cause the diiusion of i v"them to repeatedly come in contact With the inner wall of the flue, Which obviously reiiuces their temperature to approximately the same as that of the Wat-er, before their escape. The flue not only receivesthe heat. from the burned gases, but is further heated by radiation from the chain 16, which in turn receives its heat not only from the ris` ing gases but also directly 'from the Haine through the conductivity of the metal of which it is made. ln this way l am enabled to economically and'eciently heat the Water.

Having thus described my invention, I claim as new and desire vto secure by Letters Patent:

The combination of an uprighthot Water storage tank, :i feed pipe und a hotwzil'er sition of the spreader relatively to the 10 return pipe respectively lendingfroni and burner.
